    Spend a little more $

    I have never seen a tire that will get punctured by a regular small grass sticker. unless you only ride on a groomed mx track I would not buy, and the beads are always leaking. You get exactly what you pay for here.

    Great value

    For the price you can't beat these. They hook great but still break loose enough for the powerslides. Are they holeshots? Of course not , but they're also alot more affordable.

    Perfect !

    These tires are exactly what my Ranger needed! Fast shipping, fits perfect, could not ask for better experience. Much to my surprise, the ride did not suffer near as much as I would have expected from going so much more aggressive than stock.
